The Compendium of Environmental Sustainability Indicator Collections, Version 1.1 contains 426 indicators for 239 countries
from five major
environmental sustainability indicator efforts: the 2006 Environmental Performance Index (EPI), 2005 Environmental Sustainability
Index (ESI), 2004 Environmental Vulnerability Index
(EVI), the Rio to Johannesburg Dashboard, the Wellbeing of Nations, and 2006 National Footprint Accounts. It also incorporates
38 ancillary variables such as region name, dummy
variables for landlocked countries and small island states, population, GDP, and land area. The collection is compiled and
distributed by the Columbia University Center for
International Earth Science Information Network (CIESIN).
To make the acquisition, comparison and analysis of sustainability indicators easier by compiling them in a single database,
incorporating
multiple country codes, and condensing the indicator descriptions into short methodological summaries in an accompanying data
dictionary.
